The reference 5500 also known as the Pagoda - not tone mixed up with the original Pagoda ref 1593 was released in 1997 by P ate to celebrate the opening of their con]mbined watch making facilities at Plan les Oates. It was released in 3 metals YG 1100 WG 250 and plat 150. The movement was the cal 215. After release together with a special box , medallion and certificate , the original old was destroyed so it could never be replicated again
For some reason it has never been a financial success for collector ( available for little more than retail 25 years ago )but it I think it is a wonderful watch with lines and curves , Enjoy
